Description

Technical Field

[0001] The utility model relates to the technical field of textile machine equipment, in particular to a warp tension adjustment component for a rapier loom. Background Art

[0002] The rapier loom is the most widely used shuttleless loom at present. In addition to the characteristics of high speed, high degree of automation and high-efficiency production of shuttleless looms, its active weft insertion method has strong adaptability to variety and can adapt to the weft insertion of various types of yarns. In addition, the rapier loom also has obvious advantages in multi-color weft weaving and can produce yarn-dyed products with up to 16 weft colors.

[0003] When the existing tension adjustment device adjusts the tension of the warp and weft rollers of the rapier loom, the tension effect is caused by the movement of the steel sheet to expand the roller body. The tension adjustment process is difficult to ensure smooth and stable movement of the roller body, and it is easy to cause local fracture and misalignment of the fabric during the adjustment process.

[0004] This case was created to solve the above problems. Utility Model Content

[0020] The present invention will be further described in detail below through the accompanying drawings and examples.

[0021] like Figure 1-4 As shown: a warp tension adjustment component of a rapier loom, including a side plate 1, an outward expansion structure is provided on the side plate 1, the outward expansion structure includes a connecting rod 5, a displacement plate 6, and an outer wall 3 of the tensioning roller. A cylinder 7 is provided on the other side of the side plate 1, and the output end of the cylinder 7 passes through the side plate 1 and is connected to the displacement column 2. The displacement column 2 is sleeved on the fixed column 8, and the fixed column 8 is threadedly fixed to the side plate 1. When the tensioning roller needs to be expanded, the displacement column 2 is driven by the cylinder 7 to move to a position away from the side plate 1. At this time, since the end of the displacement plate 6 is fixed in the limiting groove 9, the connecting rod 5 rotates downward with the part connected to the displacement plate 6, and the displacement plate 6 is lifted up and moves outward along the limiting groove 9, and the outer wall 3 of the tensioning roller expands outward. During the whole process, the cylinder 7 acts as a constant driving force to ensure smooth and stable outward expansion movement of the roller body.

[0022] The displacement column 2 is fixedly connected to a fixed plate 4 on the circumference, and a plurality of connecting rods 5 are provided on the fixed plate 4. The plurality of connecting rods 5 are arranged at equal distances. The plurality of connecting rods 5 can firmly support the outer wall 3 of the tensioning roller and the displacement plate 6 to prevent them from breaking and falling.

[0023] The other ends of the multiple connecting rods 5 are fixedly connected to the displacement plate 6, and a limiting groove 9 is provided on the side plate 1. One end of the displacement plate 6 is slidably connected to the limiting groove 9, which fixes and limits the displacement plate 6 and better supports the outer wall 3 of the tensioning roller. The limiting groove 9 limits the moving distance of the displacement plate 6, so that the outward expansion of the outer wall 3 of the tensioning roller is controlled within a reasonable range to prevent excessive outward expansion from causing local faults and misalignment of the fabric.

[0024] The displacement plate 6 is fixedly connected to the outer wall 3 of the tensioning roller, and multiple outer walls of the tensioning roller 3 are circumferentially arranged outside the displacement column 2. In the initial state, the multiple outer walls of the tensioning roller 3 are merged into a circle, which will not cause damage to the fabric. When expanding outward, the multiple outer walls of the tensioning roller 3 expand outward synchronously and the arc surface contacts the fabric to prevent the fabric from breaking. The overall size of the tensioning roller is changed by expansion to adjust the tension on the warp.

[0025] Multiple displacement plates 6 are of the same size, and an empty slot is provided on the side plate 1. The size of the empty slot is larger than the size of the displacement plate 6. When the cylinder 7 drives the displacement column 2 to move forward, the end of the displacement column 2 penetrates into the empty slot. At this time, the connecting rod 5 rotates backward with the connection with the displacement column 2 as the center of the circle, driving the displacement plate 6 to move downward, realizing the contraction of the outer wall 3 of the tensioning roller, and further adjusting the tension of the warp.

[0026] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
